There's already an Unreal Engine package thing that includes the first UDK one so I'm sure they'll add this to that. A 2 pack would be nice for some people though because they might not want/need all 5 DVDs in the Unreal pack.
haha, the UDK bundle would just be the 2 UDK specific DVDs we have. The Unreal Bundle will have all 6. Oh, before I forget, anyone can get 20% off on the DVDs if you go through UDN. (excludes bundles) http://udn.epicgames.com/Three/Eat3D.html
Also take a look at the bundles. The ENTIRE catalog sells for $495 when buying them one by one would cost over $900. There are also tiny bundles like the Unreal bundle which helps you save about $20 on each DVD. Take a look around the site and know the market before you post stuff like that.
Either way is really fine. The way it works on UDN is you just fill a form out and it sends us an email from that form, then we enable a coupon code and send you the code to use at checkout. So either way you are buying it from the eat3d website. Also none of us are making tons of money off Eat3D. It wasn't until a year…
